View Full Version : Crossfire - ATi's version of Multi Card Rendering!
I am hearing this,
ATi's crossfire will work with one special "crossfire" card and an ordinary one. The other card can be from different vendor or make etc.
It's best to pair a 16 pixel pipeline card with a 16 pixel pipeline card, and 12 with a 12. If u pair a 16 with a 12, it will default to 12 pixel pipeline on both etc. Oh they will work with AIW cards too. More info coming soon.
Crossfire supports 3 modes of Multi card rendering. Tiling, Scissors and AFR. It will be enabled by defalt and *all games" are supposed to work with it off the bat.
Crossfire cards have a special onboard chip that will I think patch the scene from both cards and send it to the monitor to display?
Supposed to work on any 16X multiple PCI E slot motherboard. They will put emphasis on their own x200 chipsets first but, then VIA, Intel and...lastly nForce4 maybe.
Their surroundview will work from the word go
Crossfire cards will be available end of June onwards.

Good news, but everytime I think of the word "crossfire" I think of a ridiculous talking-heads show on CNN that is the butt of a lot of Jon Stewart jokes here in the US.
Than there is that car so i guess it makes it better. Yay crossfire, and all that jazz.

So, is that anything like the "any key" that people keep calling tech support, as they have trouble locating it? :angel: Seriously though, one of my class mates in Cisco 4 last semester had worked tech support, and he said he really did get those :D
Out of curiosity, by any make and model, just how open is this? I'm assuming they have to all be ATI based cards, but in terms of generations?
Limited to x800, x850 series apparently
What about a 24 pipe and another 24 pipe :p mmm

In my opion ati's crossfire is superior on paper in terms of features. The success of it will belong to the real world performance. A propos performance, a friend of mine send me some figures:
UT2003 +30%
RTC Wolfenstein +70%
Splinter Cell +90%
I hope he is right about it :-)

what is crossfire card (Special).
"AIw" stands for? all in one wonder?
Crossfire supports 3 modes of Multi card rendering. Tiling, Scissors and AFR
now what is scissors.?

1. CrossFire Edition cards include a “compositing engine” chip on-board.
2. AIW stands for ALL-In-Wonder
3. Scissor seems to be something like NVIDIAs Split Frame Rendering

still didnt get it. wats compositing engine chip?

I think that the crossfire engine chip.
Months ago people were chatted about Crossfire, it will come built-in with ATI motherboard chipsets, it will not need external connector or cable and a pair of ordinary cards will work with Crossfire with first card as master and second card as slave. It no surprise none of them are turn out to be true, the real Crossfire turn to be a master card with onboard crossfire engine chip. I think Crossfire cards will be $100 more than a ordinary card with the same spec if it come with DVI cable supplied, DVI cable are not cheap as you think, I bought my DVI cable for LCDTV at £50 near 2 years ago, that translate to $100 but the price never dropped near 2 years on. It seem SLi cards with SLi bridges are cheaper to make than Crossfire cards with DVI cables.
It's best to pair a 16 pixel pipeline card with a 16 pixel pipeline card, and 12 with a 12. If u pair a 16 with a 12, it will default to 12 pixel pipeline on both etc.
Are you sure about this? I thought that they've included a rendering mode were
the card with the most pipelines does most of the job, and the other card the lesser part. If so this is ideal, you can combine 2 different generations, no need to sell your complete rig at once. Easy upgrading.

Apparently MUYA's source is the Inq's source as well.
Looks like the Crossfire cards will be priced the same as the non-crossfire cards:
X800Xl Crossfire = $299 ; X850XT Crossfire = $549 (http://www.theinquirer.org/?article=23570)

So if you stick an R520 Crossfire with an X850Pro, you'll end up with 24 pipes total? (24-12 + 12 = 24)
That makes no sense at all.

I think of that game from the late 80s where you used those small ball-bearings to knock those weird shaped things into the opponents "ditch" or whatever. You fired the balls via an attached "turret".

No, it's just like putting a stick of PC3200 RAM with PC2700 RAM. It will default to PC2700 because the 3200 can run slower, while they 2700 can't OC itself.
It says nowhere about adding pipes together. I have no idea where you got that notion from.

I still have a working unit :D

Read MUYA's posts, superkyle.
Yeah, I did. Twice. Are you sure YOU read them?
It's saying it's recommended you use two cards with the same number of pipes. If you use a 16-pipe card with a 12-pipe card, you're only going to be able to harness 12 of those 16 because it "downclocks" (for lack of a better word) to slowest card.

16 pipes to 12 pipes is not downclocking, since down-clocking is the reduction of the core speed, not the number of pipes enabled.
As MUYA said, it will reduce/disable the number of pipes, from 16 to 12, etc. It will match the lowest common denominator that is on the non-Crossfire card.
He did mention clocks, so Crossfire might also down-clock the core speeds to match as well as reduce the number of operating pipes.
In my example I mentioned the supposed 24 pipes of the R520. Using MUYA's own example, it would "downclock" (reduce/disable) the operating pipes from 24 to 12, if you used an R520 Crossfire with an X850Pro. Which means you'd end up with two 12 pipe cards, which isn't as good as just one 24 pipe card.
I'm starting to remember why I stopped visiting the fanboi forums...........

It has nothing to do with a "fanboi" forum; it has to do with you typing out exactly what I just said, but still not understanding it.
Read the post you put, asking about two 12 pipeline cards = 24 pipes. You just said the exact opposite of that post (the same thing I said) and are still saying I'm wrong.
Plus, you corrected me when I said "downclock" (even after explaining my decision to use the word) and then proceeded to use the word in the exact same fashion you corrected me for using it!
Do two SLIed Ultras = 32 pipes? No. Do two Crossfired cards = 32 pipes? No. What the hell is so hard to understand? I've read and re-read MUYAs posts and STILL nothing jumps out at me and says your original assumption is correct. So, I'm still wondering what is so hard about all of this?

Crossfire....meh...sounds like that horrible show on CNN.
And dude 2 posts above...stop asshatting, "down-clocking" is just our generic term for matching the crappier card.
Dude one post below me, 2 cards in sli doesn't mean you get to magically add the pipes. I suggest you stop adding your pipes, you're wasted enough as it is.
2 6800Us =! 1 32-pipe card. It also doesn't equal 512mb.
